— Hospitality Vertical Profile Introduction

Hospitality and in particular hotels are changing and evolving.

Terms such as budget, business, smart, boutique and luxury are used to describe the premises and the promised experience nurturing the guest’s dreams. The Hotel is now more than ever described by the experience, which in 90% of times the journey and experience begins with a social media interaction with the Hotel.

The booking now takes place online and often using chatbots, so the use of data gained from previous stays is important to personalize guest services and upsell. In some Hotels the stay is staff less, such as in the case of the Air B&B concept and even the case for large franchises where the single biggest problem is staff retention, so any reduction is staff is advantageous. Any stay in a hotel is now going to be a digital experience in common area as well as room level from the use of non-touch biometrics, wayfinding, and a frictionless experience with, for instance, Bluetooth heat mapping to avoid queuing, congestions and maintain social distancing. Environmental issues will also figure in guest decision making on where to stay, water consumption, fuel usage even down to reuse of bathroom towels, less frequent bed changing, and chemicals used in cleaning being a deciding factor and differential for hotel groups.

By providing, a clear environmental commitment, curated services, with personalized suggestion of services drives revenue and avoids Hotels competing only on price.

The best in room level automation and environmental services translate into revenue as well as electrical distribution ensures continuity with high levels of service availability.

In the future digital solution will allow integration of system components to achieve the digital reality in hotels of the future.

— Arrival

The Guest chooses a hotel during the pre-arrival stage of the guest cycle.

The arrival stage of the guest cycle includes registration and room assignment process.

Choice of the guest can be affected by many factors, including previous experiences with the hotel, advertisement, word of mouth referral by friends and colleagues, location, corporate, travel agent booking, hotel name, hotel loyalty program member etc. The guest's decision of making the reservation can also be affected by the ease of making the reservation and the way reservation agent interacted and described the facility of the hotel like room type, room rate, recreational facilities and other attractions near the hotels. The reservation contains details of the guest specific request which will help the hotel to provide the guest with personalized service during his stay. Many Hotels are currently providing virtual tutor of hotel facility, In Room amenities, facilities inside the hotel to attract customers.

After the guest arrives, he or she establishes a business relationship with the hotel through the front office. It is the front office staff responsibility to clarify any query of the guest especially the details of room rate of packages he/she is booked on. A Registration card or registration card is printed and completed at the time of check-in, which will help the front desk to collect essential information. The registration card should contain details like billing instructions, reservation details, number of adults and children occupying, address, passport and visa for foreign nationals, full address, personal details and credit card details. Hotels can also provide guests with remote access key which can be installed on the mobile and via BLE technology the Room can be accessed without any card. During the pre-arrival if guest has provided details with regards to an electric car, an access code can be provided to the guest for a parking space and charging his/her electric car.

— Guest journey and expectations

— Occupancy

— Departure

As the main contact centre for hotel activity, the front ffice is responsible for coordinating guest requests.

Guest services and guest accounting aspects of the guest cycle are completed during the cycle's fourth and final phase i.e., departure. At Departure, the guest vacates the room, receives the accurate statement of the settled accounts, returns the room keys, and leaves the hotel. Once the guest has checked out, front office updates the rooms availability status and notifies the housekeeping department. (For hotels using Property management software the status of the room is updated automatically). At the same movement all lights, HVAC & non-essential power outlets go to energy saving mode, in most cases light and non-essential sockets power outlets are switched OFF and HVAC (temperature) of the room is set between 24-26°C At this stage front office also collect the feedback of the guest experience in the hotels by handing over the guest feedback form.

Among those providing information and supplies to the guests. Front desk should take extra care to respond to the guest in a timely and accurate manner. The focus of the front desk staff is to provide anticipatory service and to meet or exceed the guest's expectations. This will encourage the guest to repeat to the hotel. Security is also a main important concern during occupancy of the guest. Issues like protection of funds and valuables are among those. The front desk should also follow the hotel standard operating procedure for handling the hotel and guest keys, property surveillance, safe deposit boxes, guests personal property, and emergencies are also important. A variety of charges restaurant charges, telephone, internet, travel desk etc. during the occupancy stage affect guest and hotel account. Most of these charges will be posted to the guest account according to front office posting procedures.

— Features expected from hotel solution Automation, control and supervision

— Communication

The communication between different sub-systems within the same building or the visualization via the internet of images of the rooms following an alarm, are functions easily achievable in a bus system.

The main points to be considered are:

• Simplicity of wiring Using bus technology wiring for the connection between the devices, all data and information travel on a simple twisted pair, thus saving on the material and time spent laying the cables. Using a 6-conductor cable, you can also bring power and speech to the various devices. The possibility of using a simple 6-conductor cable compared to the considerable bundle of cables (or the large multipolar cable) traditionally used, considerably facilitates installation, reducing installation times. • Modularity By turning to systems that use modular technology, it is possible to make the system evolve over time, starting from the basic functions and subsequently adding the other functions, without nullifying the investments already made. • Continuity of service and ease of maintenance By taking advantage of the internal self-diagnosis and anomaly recognition functions present in some systems, it is possible to immediately identify any faults. If necessary, the electronic modules can be replaced without having to interrupt the operation of the system, thus ensuring continuity of service. In addition, the electronic room control modules, if installed in the corridor, could be replaced without having to enter the patient’s room. In this way, no disturbance is caused to the patients and doctors and nurses can safely continue to operate according to their needs, while the technical maintenance staff can intervene promptly.

A bus system can satisfy communication needs related to security, control and entertainment such as the activation of video surveillance cameras or the sending via internet of images of the rooms following an alarm, it allows to understand if there is really the issue or if it is just a false alarm. All the functions implemented in the various systems of a building can also be controlled remotely through the use of web servers or remote controllers on land or mobile networks. The video system becomes an integral part of the automation system, allowing, among other functions, communication between the different workstations within the same structure. The different communication solutions between staff and between them and occupants allow for important results, including ease of use, savings in installation and management and improvement of the service offered.

— Comfort

— HVAC control - Comfort and efficiency in the same architecture

The increase in the comfort offered by the building and the quality of living are among the best known advantages of an automation control system. Lights and shutters of a room or a series of rooms can be grouped so that they can be controlled automatically or autonomously even by fragile people. This allows to conveniently turn off all the lights in an area with a single gesture, close the windows, put all the systems you want in standby condition (e.g. cooling), activate alarms, etc. By integrating the traditional functions of an electrical system with the control and automation functions of communication to and from the building, the usability of the structures is increased. Through thermoregulation, the system plays a fundamental role not only in minimizing consumption, but also in improving comfort. People with disabilities or with temporary or permanent mobility limitations can receive assistance in using the spaces and their functions. The solutions that in most cases meet these needs can be: • video surveillance cameras; • dedicated voice commands; • remote controls with specific features such as large illuminated buttons; • large parade buttons; • alarms reported on mobile phones in case of detection of flooding, gas leaks, open doors or windows, etc; • emergency call with dedicated or pull button.

— Features expected from hotel solution Energy Management

— The tools for managing and controlling building energy consumption

— Building Energy Manager System expected features

Energy Managers, building owners, and Facility Managers are all too familiar with the pressure to reduce costs and energy consumption while maintaining occupant comfort. Energy management includes planning and operation of energy production and energy consumption units as well as storage and energy distribution. Objectives are resource conservation, climate protection and cost savings, while the users have permanent access to the energy they need. It is connected closely to environmental management, production management, logistics and other established business functions. In this sense, the choice of tool for managing and controlling building energy consumption and costs together with the BMS and the electrical power distribution scheme constitute the fundamental elements of the design of an electrical system, on which the analysis and development of the solution will depend. The ideal tool for managing and controlling building energy consumption and costs is user friendly, reporting and charting are so intuitive and easy to understand that it is not limited to use by expert energy managers. The solution shall be tailored to meet the individual requirements of each customer. The right solution focuses on energy management in order to analyze energy consumption and target savings in a building, enabling energy efficiency improvements and the continuous commissioning of the building.

Cloud-based BEMS access to the meter and sensor information in the building over the internet. The information is collected from the BAS via a secure fixed IP connection and the end-user accesses their information by logging into a dedicated website using their unique username and password. No limit to the number of meters and sensor points you can connect to the service across any geographical location is essential for large organizations but useful also for any other context. The possibility to works with any third-party systems such as Tridium, BACnet, and standalone systems via the SQL or MS Access database where the meter and sensor information is stored is crucial to avoid any limitation in existing building as well as in fully new installations.

— Analysis and charting

— Increasing awareness & encouraging behavioural change A web-based public information display can communicate information on a building’s energy performance and provides tips and recommendations of how employees can assist in reducing energy consumption. By publically engaging people in energy efficiency behavioural change, there is the potential to improve energy efficiency by a further 5% over other energy efficiency measures in an organization. It also goes beyond the building bringing this positive behaviour into the wider public arena. • Improve building energy performance • Energy savings of up to 5% over other energy efficiency measures through behavioural change • Reduce cost and carbon footprint • Communicates energy policy & strategy to the public • According with ISO 50001

— Reporting

The BEMS analysis and charting shows how, where, and when energy consumptions are. Energy consumption data can be analyzed in a number of different ways from spectral analysis displays, regression analysis, actual versus target graphing, and lots more. Charting: • View real-time energy information in day, week, month, year and custom view • Compare time periods, meters and export data Analysis: • View energy patterns using the Spectral Analysis tool • Set targets based on driving factors or fixed parameters • Compare actual versus target • Access regression analysis, overspend and cumsum charts • Analyze energy consumption compared to a smart target for real-time energy management

Reports are an important tool for ongoing energy control by helping managers and key decision-makers keep track of energy-saving initiatives, verify if and where savings have been made, and when targets have been achieved. Fully customized reporting feature allows to generate instant or scheduled reports on energy consumption, costs, carbon emissions, performance versus targets, as well as tenant costs reports.

— Monitoring and alarms

Alarms viewed via the map based interface are particularly useful for a quick overview of multiple buildings in multiple locations for bureau or monitoring centres: • Anomalies detected in energy consumed versus expected consumption • Alarm reports issued via email • Analysis of historical alarms can help identify potential ongoing issues.

There are no real specific technical standard references for the choice of the electricity distribution scheme, also in consideration of the fact that this choice is necessarily free and dependent on the process served. Electricity distribution systems are a fundamental infrastructure for most business processes and help to determine their performance in terms, for example, of energy management, safety, reliability and maintainability. If plant safety is an essential property as a legal requirement, reliability, availability and maintainability are instead characteristics of the plant that directly impact the business.

Hospitality building should be equipped with a modern infrastructure EV charging stations, the access is from a ramp with automatic access control and power supply is configured for EV chargers. The power distribution is dimensioned so that all chargers can operate at the same time at full power; in the future the user will have the possibility to increase the number of EV chargers without modify the installation thanks to reserve designed and to the load management function. Load management makes sure that the available capacity of the building is not exceeded. At times when the current demand is high, the EV charger will pause the charge session. The charge session will start again when there is availability on the grid. Slow charging is perfect for employee cars staying for the whole day in the parking, while fast chargers are perfect solution for parking place reserved for visitors, enabling re- charge in a shorter time. The charging unit should be connected to the internet via GSM, WiFi or LAN for perfect integration into smart building system and configuration via app. Simplified authentication via either RFID or App provides flexibility for public-use case applications. Protection and safety of power supply are ensured by protection devices and automatic switches. Consumptions are kept under control and energy meters are integrated into BMS for the asset management.

— Etihad Towers Abu Dhabi

The Etihad Towers - a building complex in Abu Dhabi - consist of five unique towers. Ranging from 54 to 75 floors they offer a hotel, apartments and offices. The highest tower reaches a high of over 300 meters and the whole complex covers half a million square meters.

Results The system detects the occupancy in the guest room and switches between energy saving and guest comfort mode. There is a huge saving (around 30%) by controlling the guest room HVAC, lighting and curtain control system. The system will change the set point and fan speed (fast cooling mode) from the reception once the guest checks in from the reception desk. The lighting control in the common area includes controlling of circuits through time schedule and occupancy. 30 % saving compared with study for conventional GRMS (Guest Room Management System).

Offering a total of 884 apartments and penthouses with up to 5 bedrooms, the three spectacular residential towers provide also a wide range of fashion and relaxation amenities. With a total of 602 hotel guest rooms and serviced apartments the hotel tower stretches up over 60 floors. The state of the art office tower features a well-designed infrastructure and proficiently managed facilities. Furthermore a wide range of shopping facilities, a four level underground car park with a capacity of over 3,000 cars, a large convention center and a grand ballroom for up to 2,200 guests are contained within this stunning complex. Challenge The solution should be economical, easy to operate for the guest and user friendly for engineering, housekeeping and reception staff. Furthermore the system had to be integrable to the Property Management System (PMS) and Building Management System (BMS) by an open protocol. A maximum utilization of energy with less wastage and with high efficiency as well as energy saving via presence sensing instead of a card switch was required. A visualisation which covers the common area control system, current consumption and lamp operation hours was also an requirement which had to be fulfilled. Solution The customer required a state of the art facility with convenience access to all guest room functions in addition to a multivendor technical platform to be future proof. The common areas such as corridors, basement parking areas and lift lobbies are controlled by a lighting control system. The user interface should be simple, easy to operate and at the same time user friendly for the reception, housekeeping and engineering staff. It was required that the system shows the current consumption for each circuit and calculates the lamp operation hours.

— Hotel Neu – Heidelberg

The family managed three stars superior (3* +) Hotel Neu Heidelberg welcomes its guests with a pretty entrance hall. The innovative and state-of-the-art KNX technology provides the background for both, a pleasant atmosphere and an energy-efficient operation. This shows that smaller family managed properties benefit from KNX Intelligent Building Control as well. The hotel offers 44 hotel rooms of different categories of which 28 are located in the new building which has been finished in September 2012. In addition to a pleasant atmosphere for tourists and business travellers, energy efficiency is a focus issue to minimize operational costs. For example, the building uses geothermal energy for passive cooling, a block heat and power plant is used for heating and for the generation of 67 % of the electricity required, the elevator feeds electricity into the in-house grid and the 15m² solar heat system on the roof supplies hot water. This belief, that pioneering technology is the key to an economic hotel operation, is also shown by the new building which is an annex to the existing one (constructed in 1950). The efficient room climate control is supported by thermo-active ceilings respectively thermo- active gypsum walls and dormer cover panels at the top floors. Additionally, separated networks for fresh water and grey water ensure that the shower water can be used for the toilet flushing. Furthermore, the new building is lit by LED lights to minimize energy consumption and maintenance. Challenge It was a special challenge to provide a unique atmosphere for the guest with the help of KNX. To achieve this, RGB lighting was implemented at the reception to welcome the guest with a specific mood which e.g. depends on the outside temperature and weather conditions. It was a further challenge to combine an energy-efficient operation of the hotel with a high guest comfort. Solution The decision to use KNX was made due to the compact and cost-efficient ABB Room Master devices. Instead of installing multiple KNX components for controlling one hotel room, a single KNX device combines various actuators and sensors. The installed Room Master Premium RM / S 2.1 is used to connect conventional pushbuttons and to control consumers such as lights, sockets and shutter drives.

With the Room Master extensive comfort features have been implemented. The floor lighting of the hotel room is switched off after a specified time when pulling the room key card. For achieving a convenient atmosphere various predefined light scenes can be called by using the controls of the switch series Future Linear of ABB Busch-Jaeger. A pleasant room climate is achieved by using the room thermostat RDF / A 2.1 in conjunction with the electronic switching outputs for controlling the valves. Additionally the hotel rooms can be set with a special "check-in function" to a specified room state. Once the guest checks in at the reception, the heating control is set from "standby mode" to "comfort mode", the shutters are raised and the hotel room TV displays a welcome message. Furthermore a monitoring of the rooms' consumers via a visualisation helps to identify energy wasting. Results A daylight-dependent control of shutters in combination with a KNX Weather Station helps to reduce the cooling demand of the hotel rooms. Furthermore, a presence dependent lighting control of public areas is realised with presence and motion detectors. If no movement or presence is detected, the brightness of the lamps is reduced to lower power consumption. Additionally, lighting and heating control of the hotel rooms is adjusted by a key card switch. If the guest is absent, the lighting is switched off and the setpoint temperature is reduced.

— Corridors & Public Rest Rooms

Stairs & lobbies provide warm ambience to the guest by maintaining set lighting intensity and temperature, air quality at the same time providing energy efficiency with the use of occupancy detection to set the light & temperature at levels to provide maximum comfort and energy efficiency.

Hotel corridors, stairs & public rest rooms Lighting & HVAC can be easily controlled and continuously monitored.

Hotel corridors, stairs & public rest rooms are equipped with Lighting & HVAC control system & continuously monitored by a central sever for different alarms like fault in light fixtures, if the set temperature demand is not achieved, higher level of CO 2 , humidity and based on those corrective actions are taken example is CO 2 level increases FAHU or Ventilation is opened to bring in fresh air. Maximum energy efficiency is achieved with the use of PIR sensors or staircase lighting functionality where the lights are switched OFF or dimmed to a lower level if no presence is detected. Also, these areas are equipped with emergency Lighting signs which are continuous monitored from the central software or from the APP for battery status, brightness level, etc.

These areas installed with emergency light and integrated with CCTV & security alarm system and can be monitored from central sever.

GRMS System for controlling of Lighting, Shading, HVAC access control, AV control provide comfort and unique guest experience.

The control room maintains and secures backups for the different systems running in the hotel from front desk to access control system. It also monitors and controls (in case of emergency) the components inside a guest room example checking from the central sever is the room temperature is archived in case of supply air issue which is not allowing the HVAC control system to meet the demand temperature set in the room. Also, other common areas of the hotel like stairs, parking, restaurants, cafes, lobbies areas all system like lighting, diming & emergency light are monitored and can be controlled from the central sever station. Central sever also monitors power distribution components for critical load management and all alarms, conditional monitoring can be done via cloud. Access Control software is based on a client-server architecture. For small installations it is possible to have server and client instances on the same PC/machine. For bigger installation server instance is usually installed in the server room of the hotel. It is important that when required the IT manager of the hotel properly configure the IT network infrastructure in order to let Access Control software server communicating with clients and third-party PMS software.
